TOILET-PAPER CUTTER.

Application led September 3, 1918.

roll and rotary cutter type, and the machine y is designed especially for use in a vending apparatus or coin machine, for dispensing sanitary seat covers for toilet use.

In the present invention "a feed roll of paper is employed, and by the utilization of a rotary cutter andoscillating knife, sheets of the roll are successively cut and severed from the roll, the feeding of the roll being in the form of a `folded strip, so that the rotary cutter may cut a tongue from the sheet before it is severed by the oscillating or pivoted knife.

The invention consists essentially in certain novely combinations and arrangements of the actuating parts of the machine involving the coin mechanism and sheet severing mechanism as will be hereinafter more fully pointed out in the claim. y

Fig. 9 is a diagrammatic View showing the tongue cutting rotary knife.

The seat cover, as it issues from themachine, is folded, as indicated at 1 Fig. 7, and this sheet has cut therefrom an ellip tical tongue 2, to be used for protective purposes, leaving a central opening 3 in the sheet when unfolded, which is cut on line 4, and a neck 5 is provided leaving the tongue attached to the sheet, so that yit may be folded down within the seat opening for sanitary purposes. These seat covers are dispensed from the box or housing 6 through the slot 7 in the front thereof by means of the instrumentalities actuated by the crank 8 and the chopping lever 9, the crank located on the outside of the machine, and the lever projecting through the front of the housing in slot 9.

lVithin the housing is arranged and fixed a suppoiting frame 10 for the operating parts of the device, and Within the housing and frame the two rollers 11 and 12 are journaled, and the rollers are'held in frictional contact by means of the side springs 14:, which connect the two shafts 15 and 16 of the respective rolls.

The two rollers are e uipped with a rotary cutting device in the orm of a circumferentially arranged cutting knife, preferably with a serrated edge, as 17, and the upper kroll has a complementary recess 1S to receive this knife or cutter. The special arrangement of the cutting device will be apparentin Figs. 2 and 9 where i-t will be seen that the front end of the knife or cutter starts at the end of the roller, and thereai* end or finish of the cutter is located a short distance from the end of the roll, thus providing for cutting of the tongue 2 Without actually severing 1t from its sheet, by leaving the neck attached to the sheet. The sheet or seat cover is severed from the strip by means of the longitudinally extendino pivoted knife blade 19, pivoted at 20 1n the. frame and co-acting in conjunction with the slotted vertically arranged plate Q1 having the delivery slot 2Q, and extending across the machine in front of the rollers between the frame members to which it is secured. Preferably the knife is shorter than the Width of the paper strip as it issues from its rollers, so that the sheet is not severed nection with gear wheel :29'to prevent re-` verse movement of the rollers.

entirely' frpm the. strip, but is left dangling` in front of the machine after having been delivered through the slot 7, and as the cover emerges through the slot it is to be torn off, by hand, when grasped by the operator.

The two fold web or stri i is wound upon the spool 23 journaled in tie long inclined slots Qtso that the journal ends of the spool may be guided in the slots as the size of the roll decreases, andthe roll rests upon the top of the upper roller 11 as a support, the end ofthe strip being fed downwardly between the two feed rollers 11 and 12, through the deliver 1 rolls QG and 27, thence through the slot Q2 1n the plate Q1 for action by the knife 19.

The cutting rollers 11 and 12 are actuated from the crank handle '8 on the shaft 15l through the Jair of gears Q8 and 29 meshing with each ot ier and at the ends of these two rollers, a pawl 30 being employed in con- The gears are held locked by means of a bell crank lever 31, pivoted at 32, and held otf center by means of the spring 33. and the pawl 3i secured at the inner side of the short arm of the lever engages the teeth of the gear "28 see Figs. 3 and 4. The cutting rolls are normally held locked by the pawl, and the pawl is unlocked only by the presence of the chute 35 of a check, in the form of a penny 36, which, when moved or forced downwardly by the pin 37 on the chopping lever, en

gages a slide lever 38, somewhat S shaped and pivoted at 39 on the free end of the bell crank lever 31. Lever 38 is slotted at 40 and a guide pin 41 fixed to a part of the chute 35 permits a limited swing of the slide'lever or re-locking lever on the point 39 as a center and of course the slide lever swings bodily with the bell crank lever on its cen-y ter 32. The pawl 34e is` disengaged positively by action' of the pin 3T of the chopping lever and the'coin in its engagement. with theslide lever 38, and the paivl is again made to engage the teeth of gear 28 when the pin 43 on the lower, roller 12 comes around at the end of the cutting stroke of cutter 17, to strike the cam face 12 of this slide lever 4or cam lever 38, the encounter of the pinfand cam face,`or course, swinging the bell crank lever over to the left as in Fig. 3. and returning the cam lever 38 to' its normal position as seen also in Fig. 3.

The pivoted knife 19 is held in normal postion by the spring 33 and it will beyseen that theknife closesthe deliverychute 22 when in normal position. The cutting stroke `of the knife is an upward swing on its pivot 2O under tension of the springv33, and the knife is moved from normal position to operative position by means of the chopping lever 9 which has a depending arm 43 and roller 454C engaging the cam arm 45 at the end ofthe knife blade and extending to the rear at right 4angles thereto. lVhen the chopping lever is depressed against the tension of its spring 9, it swings the knife blade 19 spring 50 against the projecting pivot pin 39 of the cani lever 38. The pivot pin 39 projects through a slot 39', in the frame 10 and the spring 50 normalhv holds the latch against this pin, but as the lug -lG rides down on the cam face 51 of the lug 47, the latch is swung to the right in Fig. 5 to permit the lug 4G to pass. when the spring 50 immediately retracts the latch 18 so that the cam lug 47 holds down the cam arm 45 by engageineiitv'ith the` lug 46 thereon. After the knife is held down to its operative position, the spring 9"L retracts the chopping lever 9 to position in Fig. 5 leaving the knife in the dotted position shown. The crank arm 8 is then turned, and,l after the end of the cutting stroke of the rotating rollers, the lug 13 encounters the cam face 42 of the cam lever, lifting the lever and with it` its pin 39, which encounters the cam shoulder of the latch 48 and swings the latch to the right in Fig. 5. T hereupon the tivo lugs 1G and 47 are disengaged and the knife is swung upwardly on its pivot 2O by its spring 33. Thus, the first action after placing the penny in the chute or slot is to depress the chopping or operating lever 9 which action simultaneously disengages the pawl 31 from the gear 28 and moves the knife 19 to operative position. after which the chopping ylever is permitted to returnto normal position by means of its spring 9a. After the parts are in position as described, the crank handlev 8 is given a complete' turn from t-he horizontal position indicated in y Figs. 1 and 5, and the desired length of strip v (Figs. 5 and 6) to drive the rollers, as well understood, and after the required length of strip, with its cuttongue. has passed through the deliveryslot 7, the latch 48 is freed as described, permitting the knife 19 to swing upwardly on its operative stroke, severing all but the right end of the strip (see Fig. 4). The strip is left dangling by the uncut portion, and is then torn o by the operator in Well known manner.

Claim:

The combination with a rotary cutting device including e pair of feed rollers with enga-ging gear Wheels, of a locking device therefor comprising a bell crank lever and a spring for holding it off center,I a cam lever Jivoted on the bell crank lever and a pawl Xed on the bell crank lever to engage one of the gea-r Wheels, mechanism operative in the presence of e coin for actuating the 10 cam lever to move the bell crank lever for disenguging the pawl, and means on one of the rollers for actuating the cam lever to return the pawl to locked position.
